I was just going to write about this.
Yes that is exactly the problem, the I3DL2REVERB effect is failing with a REGDB_E_CLASSNOTREG (class not registered) error.
So it is a bug introduced in the Windows 11 24H2 build 26100.3476.
A previous Windows 11 24H2 build 26100.2605 does not have that issue. Just like any other 23H2, 22H2 builds.
I already open a ticket at Microsoft regarding this. I added this information today.
Thank you
